不知道什么是错的，但我得到这个错误从Chrome的控制台：
jquery-3.2.1.slim.min.js:1244 jQuery.Deferred exception: $.ajax is not a function TypeError: $.ajax is not a function
at HTMLDocument.<anonymous> (file:///C:/Users/Adam/Desktop/UseTime/js/example.js:3:7)

at HTMLDocument.<anonymous> (example.js:3)
at j (jquery-3.2.1.slim.min.js:1193)
at k (jquery-3.2.1.slim.min.js:1199)
从这个JavaScript：
$(function() { //when the DOM is ready
var times; //declare global variable
$.ajax({ //set up request
beforeSend: function (xhr) { //before requesting data
if (xhr.overrideMimeType) { //if supported
xhr.overrideMimeType("application/json"); // set MIME to prevent errors
}
}
});
//funciton that collect data from the json file
function loadTimetable() { //decalre function
$.getJSON('data/example.json') //try to collect json data
.done(function (data) { //if succesful
times = data; //store in variable
}).fail(function() { //if a problem: show message
$('#event').html('Sorry! we couldnt load your time table at the moment');
});
}
loadTimetable(); //call the function
//CLICK ON TEH EVENT TO LOAD A TIME TABLE
$('#content').on('click', '#event a', function (e) { //user clicks on place
e.preventDefault(); //prevent loading page
var loc = this.id.toUpperCase(); //get value of id attr
var newContent = "";
for (var i = 0; i < times[loc].length; i++) { // loop through sessions
newContent += '<li><span class = "time">' + times[loc][i].time + '</span>';
newContent += '<a href = "descriptions.html#';
newContent += times[loc][i].title.replace(/ /g, '-') + '">';
newContent += times[loc][i].title + '</a></li>';
}
$('#sessions').html('<ul>' + newContent + '</ul>'); // Display Time
$('#event a.current').removeClass('current'); // update selected link
$(this).addClass('current');
$('#details').text('');
});
//CLICK ON A SESSION TO LEAD THE DESCRIPTION
$('#content').on('click', '#sessions li a', function (e) { //click on session
e.preventDefault(); // prevent loading
var fragment = this.href; //title is in href
fragment = fragment.replace('#', ' #'); //Add Space before #
$('#details').load(fragment); //to load info
$('#sessions a.current').removeClass('current'); //update selected
});
//CLICK ON PRIMARY NAVIGATION
$('nav a').on('click', function (e) { //click on nav
e.preventDefault(); //prevent loading
var url = this.href; //get UR: to load
$('nav a.current').removeClass('current');
$(this).addClass('current');
$('#container').remove(); //remove old
$('#content').load(url + ' #container').hide().fadeIn('slow'); // add new
});
});
我不确定这是否与我启动.ajax的方式有关，或者如果我的jquery没有正确实现。我觉得是这样的。有什么想法吗？
编辑：下面是用脚本去上面

你链接任何jQuery的你的代码？ ？在任何其他javascript之前链接jquery。它可能工作。 – AdhershMNair
是的，它是在这个HTML中调用这个，我会把它扔到后 – Adamwuh
